what could cause one of my monitors to be stuck at 640x480 only on the first boot after a system update?

when i boot my computer after having run an update, my primary monitor (which should be at 1920x1080) is stuck at 640x480. interestingly, when i reboot and change nothing, it fixes itself until i run another update.
i'm on arch, using nvidia 555.58-2, on plasma 6.1.1-1. the monitor in question is DP-0 in the system info below.
what could be causing this and how can i fix it?
i've been having this issue for a while while kinda just dealing with it because it was something i could easily work around by booting my computer twice, but i'd really like to get it solved.

relevant (i think) inxi output

Just a thought, and it seems less applicable to your situation given the software experience you've described, but I've had this happen to me with a faulty display cable. Have you tried a spare one?
that's worth checking - i don't have a spare DP cable on hand to test, but you may be onto something.
previously, i tried unplugging and replugging the cable on the PC end, as well as trying other ports, to no avail.
just now, i tried replugging the end plugged into the monitor a few times and was able to reproduce the resolution issue a single time. this honestly just confuses me more though, because why would it happen only one time out of several cycles doing the exact same thing?
i'm gonna get another cable just to be sure but that wont be for a few days at least.
in case anyone is reading this looking for a solution the cable was not the culprit
